Abstract :
Electrical power distribution system will not be separated from a short circuit and ground fault on the network whether caused by internal and external factors. Disorders that may occur can cause damage to the equipment and the distribution of electrical loads when the disorder is not immediately isolated by the protection devices. One of the primary protection in the electric power network is a ground fault relay (GFR).Protection system are discussed in the outgoing feeder protection system using GFR and calculate the current relay single phase disturbance to the ground to determine the relay settings, especially feeder Centex 1. After calculation of the fault current phase to ground fault currents obtained the biggest yes 955.87 A and 757.71 A smallest fault current and fault current calculation phase to ground one can conclude that the farther from the source the smaller the fault current flows and the closer to the source of the fault current increases. The TMS value of 0,1.
